Kr friends, Thanks for your response, One of the Dutch pilots flyes with à copy of the Tony B. Books. Installed the tubes in front of the main spar. I want to copy it but we have the leadingedge fuel tanks at that position. So we are not able to come out the wing at that position. I was in à doubt to come out off the wing just after the FwD spar.....And extend the tubes 1 fwd spar. My kr friend from all over the world make up my mind......I Will leave it like the Dutch kr friend and put is just after the fwd spar.
Thanks everybody. Stef Stef and Ted are building the KR-2S see http://www.masttotaalconcept.nl/kr2 -----Oorspronkelijk bericht----- Van: krnet-boun...@mylist.net namens Larry&Sallie Flesner Verzonden: do 13-12-2012 5:32 Aan: KRnet Onderwerp: KR> Pitot / static tube. >.

It only increases the opportunity for them to get damaged by accident. I built the very simple system as suggested in the KR plans, the same as suggested in other posts. The assembly is mounted just outside the propeller arc in the outboard wing panel. They extend approx. 6 inches below the wing and the lead edge of the tubes are nearly in line with the lead edge of the wing. Flying in a number of "no wind" conditions in the last 460 hours, the system seems to be accurate to within 1 or 2 miles per hour as compared to the GPS ground speed. Don't waste time trying to re-invert the wheel. Others have tried to find other static port locations on the aircraft but I don't see any way they will find a better location then the setup suggested in the plans. The critical part is to keep the tubes aligned parallel to the longitudinal axis of the airplane. Keep it simple and go fly.
